Hey, James Nice studies, Most of them a solid.Proportions are good enough. I see a few issues with the line quality but nothing too serious. I think you're still a little shaky drawing ovals and circles. So practice drawing using your whole arm no only the wrist. Your lines will become more confident as you get more mileage under your pencil. Answering your question. You will find more on the placement of the oval on the video on extreme angles. But, let me try to give you something until you watch the video. So in perspective the farther something is from us the smaller it will be. By that logic if we are looking up to a head we are seeing less of its top, the upper thirds will get a little smaller and therefore the oval will be higher. If you can't picture yet, drawing from the 3-d model may help you a lot visualizing it. Keep Drawing Best Regards
